Looking for bike for Nephew

Hi Guys,

I let my Nephew ride my SC twice now. He's reached out a couple of times looking for help in his search for a bike of his own. He lives in Palmdale. So far he liked riding my SC large hightower with the 27+ wheel set- but he said going down Golden Eagle that he felt totally top heavy- like he was going to go over the bars the whole time. 32 inch inseam at 6 foot tall. I believe he is only interested in regular trail riding. If you know of a bike for sale new or used most likely size XL 27.5 wheels please let me know. Maybe we can get him fixed up or steer him in the right direction. Thanks!
